NTI UNIMUX-HD4K18GB-24 (24-Port Rackmount 4K HDMI 18Gbps KVM Switch / $3333.33) Review
The NTI UNIMUX-HD4K18GB-24 is a rackmount 24-port KVM switch supporting full-bandwidth 18Gbps HDMI 2.0 at 4K@60Hz 4:4:4, with 2 transparent USB 2.0 ports, HDMI audio switching, and RS-232 control, priced at $3333.33.
The 24-port model is aimed at large server rooms consolidating racks of machines onto a single console point, and NTI holds the line on bandwidth here too — every one of the 24 ports still gets full 4K@60Hz 4:4:4, not a downgraded spec reserved for the smaller models. It sits between the 16-port and 32-port models as the mid-large option for facilities that have outgrown 16 ports but don't need the full 32. Versus the NTI UNIMUX-HD4K18GB-16 — fewer ports for less money, adequate for a smaller row of racks. Versus the NTI UNIMUX-HD4K18GB-32 — the largest model in the line, worth it only if 24 ports genuinely isn't enough.

- Large server rooms consolidating 24 machines onto one console
- Facilities that outgrew a 16-port switch but don't need 32
- Operations wanting scripted RS-232/network control at scale
Not for
- Smaller deployments better served by the 8 or 16-port models
- Budgets needing the lowest cost per port (see the 32-port model)
- Desktop or small-office use
